Description

Refrigerant-containing composition, use thereof, refrigerator having the same, and method for operating the refrigerator
Technical Field
The present invention relates to a refrigerant-containing composition, use thereof, and a refrigerator having the same, and a method for operating the refrigerator.
Background
R410A is currently used as an air conditioning refrigerant for home air conditioning and the like. R410A is a 2-component mixed refrigerant of difluoromethane (CH 2F2; HFC-32 or R32) and pentafluoroethane (C 2HF5; HFC-125 or R125) is an azeotrope-like composition.
However, R32 having GWP 675 is used more often because the Global Warming Potential (GWP) of R410A is 2088 and there is an increased concern about global warming.
Accordingly, various low GWP mixed refrigerants capable of replacing R410A have been proposed (patent document 1).

Definitions of the terms >
In the present specification, the term "refrigerant" includes at least a compound specified in ISO817 (international organization for standardization) and having a refrigerant number (ASHRAE number) starting with R indicating the type of refrigerant, and also includes a compound having the same characteristics as a refrigerant as the compound to which the refrigerant number has not been given. From the structural aspect of the compound, the refrigerant is broadly classified into "fluorocarbon-based compound" and "non-fluorocarbon-based compound". The "fluorocarbon-based compound" includes chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), and Hydrofluorocarbons (HFCs). Examples of the "non-fluorinated hydrocarbon compound" include propane (R290), propylene (R1270), butane (R600), isobutane (R600 a), carbon dioxide (R744), and ammonia (R717).
In the present specification, the term "refrigerant-containing composition" includes at least: (1) the refrigerant itself (including mixtures of refrigerants); (2) A composition which also contains other components and can be used to obtain a working fluid for a refrigerator by mixing with at least refrigerator oil; (3) working fluid for refrigerator containing refrigerator oil. In the present description, the composition of (2) is labeled as "refrigerant composition" differently from the refrigerant itself (including a mixture of refrigerants). The working fluid for a refrigerator of (3) is labeled "working fluid containing refrigerating machine oil" as distinguished from "refrigerant composition".
In the present specification, the term "replacement" refers to a case where the first refrigerant is replaced with the second refrigerant, and as the first type, means that the second refrigerant can be used to perform operation under optimal conditions by changing and adjusting the equipment as required only by a small part (at least one of the other parts such as refrigerator oil, gasket, expansion valve, and dryer) in the equipment designed to perform operation using the first refrigerant. That is, this type refers to the "replacement" of refrigerant to operate the same equipment. As a mode of "replacement" of this type, a "simple (drop in) replacement", "approximately simple (nealy drop in) replacement", and "update" may be performed in order from small to large, depending on the degree to which the replacement is required and the adjustment is performed when the replacement is performed with the second refrigerant.
As a second type, a case where equipment designed for operation using the second refrigerant is used for the same purpose as the existing use of the first refrigerant, and the second refrigerant is mounted for use is also included in the term "substitution". This type refers to the same purpose provided after "replacement" of the refrigerant.
In the present specification, the term "refrigerator" refers to all devices that take heat from an object or space to a temperature lower than the surrounding outside air and maintain the low temperature. In other words, the refrigerator is a conversion device that obtains energy from the outside to operate and converts the energy so as to move heat from a lower temperature side to a higher temperature side.
In this specification, the term "WCF micro-ignition" means that the combustion rate of the refrigerant is 10cm/s or less according to the American ANSI/ASHRAE34-2013 standard, which is the most readily combustible composition (the most disadvantageous component of flammability; worst case of formulation for flammability; WCF). In the present specification, the term "micro-ignition of refrigerant" means that the combustion rate of WCF is 10cm/s or less and the combustion rate of the most easily combustible fraction (the most adverse fraction component of combustibility; worst case of fractionation for flammability; WCFF) determined by the storage, transportation and leakage test at the time of use based on ANSI/ASHRAE34-2013 using WCF is 10cm/s or less, and it is determined that the combustion rate of ANSI/ASHRAE34-2013 standard is classified as "grade 2L".
In the present specification, the temperature slip (Temperature Glide) refers to an absolute value of a difference between a start temperature and an end temperature of a phase change process of a composition containing the refrigerant of the present invention in a heat exchanger of a refrigerant system.

The embodiments are described above, but it should be understood that: various modifications can be made to the embodiments and contents without departing from the gist and scope of the claims.
Examples
Hereinafter, examples will be described in more detail. The invention is not limited to these embodiments.
As described below, R410A (r32=50%/r125=50%) and the mixed refrigerant of HFO-1132 (E), HFO-1123 and R1234ze (E), and the mixed refrigerant of HFO-1132 (E), HFO-1123, R1234ze (E) and R1234yf were evaluated, respectively.
For each mixed refrigerant, the burn rate was measured as WCF concentration in terms of the ANSI/ASHRAE 34-2013 standard with the mixed composition. The combustion rate is "2L-grade (micro-combustibility)", when it is 10cm/s or less.
The combustion speed test was performed as follows using the apparatus shown in fig. 1. First, the mixed refrigerant used was set to a purity of 99.5% or more, and the cycle of freezing, pumping and thawing was repeated until no trace of air was seen on the vacuum gauge, thereby performing deaeration. The combustion speed was measured by the closed method. The initial temperature is ambient temperature. Ignition is performed by generating an electric spark between the electrodes at the center of the sample chamber. The duration of the discharge is 1.0 to 9.9ms and the ignition energy is typically about 0.1 to 1.0J. The state of flame propagation is visualized by a schlieren method. A cylindrical container (inner diameter: 155mm, length: 198 mm) having 2 acrylic windows through which light was transmitted was used as a sample chamber, and a xenon lamp was used as a light source. The schlieren image of the flame was recorded with a high-speed digital video camera at 600fps frame rate 600 and saved in the PC.
The combustion speed (Su (cm/s)) is expressed by the volume of unburned gas consumed per unit time by the flame surface per unit area, and is calculated by the following formula.
Su=Sb*ρu/ρb
Ρu; adiabatic flame temperature (unburned)
Ρb; adiabatic flame temperature (burnt)
Here, sb is obtained from a schlieren video image, ρu is a measured temperature, and ρb is calculated from the combustion heat and the constant pressure specific heat of the combustion gas.
The results of the combustion rate tests for the mixed refrigerants HFO-1132 (E), HFO-1123 and R1234ze (E) are shown in tables 1 and 2.
TABLE 1
TABLE 2
Based on these results, it was judged that: assuming that mass% of HFO-1132 (E), HFO-1123 and R1234ze (E) based on the total of them is x, y and z, respectively, in the 3-component composition diagram of FIG. 2 in which the total of HFO-1132 (E), HFO-1123 and R1234ze (E) is 100 mass%, a mixed refrigerant having a composition with coordinates (x, y, z) located below the line GI exhibits WCF micro-combustibility (the combustion speed of the WCF composition is 10cm/s or less) according to ASHRAE standards.
Further, it is determined based on these results that: in the above 3-component composition diagram, the mixed refrigerant having the coordinates (x, y, z) at a composition lower than the line connecting points J, P ', Q, S', N, N ', M' and M exhibits microcombustibility according to ASHRAE standard (2L-stage (combustion speed of WCF composition and WCFF composition is 10cm/s or less)).
The GWP of each refrigerant mixture was evaluated based on the GWP of each refrigerant constituting the refrigerant mixture. The GWP of each refrigerant is based on the IPCC (Intergovernmental Panel on CLIMATE CHANGE; inter-government climate change specialization committee) 4 th report value. The GWP of HFO-1132 (E) is not described in this report, but is assumed to be 1 according to HFO-1132a (gwp=1 or less) and HFO-1123 (gwp=0.3; described in patent document 1).
The refrigerating capacity of each mixed refrigerant was obtained by using the fluid thermodynamic and transport property database (REFERENCE FLUID THERMODYNAMIC AND TRANSPORT PROPERTIES DATABASE (Refprop 9.0)) of the national institute of science and technology (National Institute of SCIENCE AND Technology (NIST)), and by performing theoretical calculation of the refrigerating cycle of the mixed refrigerant under the following conditions.
Evaporating temperature 5 DEG C
Condensing temperature 45 DEG C
Overheat temperature 5K
Supercooling temperature 5K
Compressor efficiency 70%
Based on these results, coefficient of performance (COP) was obtained by the following equation.
Cop= (refrigerating capacity or heating capacity)/consumed electric quantity
Further, regarding the freezing capacity and COP, the ratio with respect to R410A is shown.
With respect to the discharge pressure, the ratio with respect to R410A is shown.
